Internet Generally speaking, a set of interconnected computer networks
communicating through a common protocol (TCP/IP). The Internet (note the
capitalization) is the most extensive publicly accessible system of interconnected
computer networks in the world.
intranet A network of computers operated by and for the benefit of an organization’s
internal users. Access is commonly restricted to members of the organization. Many
times, it refers to a web site for the organization which is accessible only from within
the organization. Intranets use the same networking technologies as the Internet
(TCP/IP), and sometimes bridge legacy information systems with modern networking
technologies.
IP Internet Protocol. Also known as IPv4. A method used with Transmission Control
Protocol (TCP) to send data between computers over a local network or the Internet.
IP delivers packets of data, while TCP keeps track of data packets.
IP address A unique numeric address that identifies a computer on the Internet.
IPP Internet Printing Protocol. A client-server protocol for printing over the Internet.
The Mac OS X printing infrastructure and the Mac OS X Server print service that’s built
on it support IPP.

segment, that shares a network address with other portions of the network and is
identified by a subnet number.

web hosting for ecommerce applications as well as mail services.
JBoss A full-featured Java application server that provides support for Java 2 Platform,
Enterprise Edition (J2EE) applications.
Kerberos A secure network authentication system. Kerberos uses tickets, which are
issued for a specific user, service, and period of time. Once a user is authenticated, it’s
possible to access additional services without retyping a password (this is called single
sign-on) for services that have been configured to take Kerberos tickets. Mac OS X
Server uses Kerberos v5.
Kerberos realm The authentication domain comprising the users and services that are
registered with the same Kerberos server. The registered services and users trust the
Kerberos server to verify each other’s identities.
LAN Local area network. A network maintained within a facility, as opposed to a WAN
(wide area network) that links geographically separated facilities.
LDAP Lightweight Directory Access Protocol. A standard client-server protocol for
accessing a directory domain.
